QRK-LDV

Description

QRK-LDV drives four LEDs and is optimally suited as a voice indicator in a QRK-style system. The shared current-limit resistor is best suited to one LED being 'on' at a time.

QRK-LDV operates from 12Vdc and provides about 10mA of LED current.  The stock LEDs are green standard-brightness 3mm round.

QRK-LDV is useful with QRK-SF or QRK-SR, but not required if either QRK-RLY or QRK-FET are present.

 Kit requires assembly.

PCB size: 1.35" x 1.1" (35 x 28 mm)
